Dear all,

The EUscreen project has recently expanded its aim to provide unified access to European television history by implementing the Linked Open Data principles and by signing the new Europeana Data Exchange Agreement.

We would like to welcome you to download the paper Publishing Europe’s Television Heritage on the Web and to contribute your comments and feedback on the EUscreen blog.
Information about EUscreen’s Linked Open Data Pilot can be found at http://lod.euscreen.eu

1. EUscreen opens up to Linked Open Data

On the EUscreen platform, 27 partners (broadcasters, archives and universities) select, curate and provide television materials from their rich vaults that together hold a great part of European audiovisual history. By mapping the schemata that underpin their content descriptions to the EUscreen metadata model, content providers ensure greater visibility and findability of their content in the public realm.

Much work has been done on uniformly processing the different metadata models to one central EBU Core-based model. This model ensures a level of uniformity that surpasses the scattered databases that the different institutions work with. The integrated collections are published on the EUscreen portal and from there on aggregated by Europeana.

With this centralised model in place, it was a relatively straightforward step to implement the Linked Open Data principles, which permit the interpretation and interlinking of the data to various sources outside of the EUscreen domain, and allow for a machine-readable level of access to the content. EBU Core provides mappings to all known audiovisual metadata standards, including the W3C’s Media Annotation ontology. The EBU Core ontology was used to formalise the metadata in the Resource Description Framework (RDF) format and publish them as Linked Open Data.

Johan Oomen, technical director of EUscreen, and Vassilis Tzouvaras, leader of the work package on portal architecture, wrote a paper on the installation of the Linked Open data model: Publishing Europe’s Television Heritage on the Web (PDF). In it, the authors describe how this fits in within the larger technical challenge of creating the different components that make up the EUscreen ingestion workflow. The paper describes the reasoning behind the workflow, the set-up and overview of the process and how these technical developments improve access to our shared television histories to students, teachers and the general audience. You can leave your comments at the end of this article for feedback. The authors would like to acknowledge EUscreen consortium partner EBU, specifically mr. Jean-Pierre Evain, for their work in the area of multimedia semantics and Linked Open Data, as their EBU Core Metadata Set has been used to ensure semantic interoperability within EUscreen and beyond.

The Linked Open Data implementation will be presented by Nikolaos Simou (Technical University of Athens, GR) on Thursday, September 29th at the International Workshop on Semantic Digital Archives, which is held in the framework of the International Conference on Theory and Practice of Digital Libraries in Berlin. You can view his presentation Publishing Europe's Television Heritage on the Web online.

2. EUscreen signs Europeana’s new Data Exchange Agreement

A second, and related, development is EUscreen’s recent signing of Europeana’s new Data Exchange Agreement, which ensures access and enlarged user involvement with the materials published on the platform. The agreement replaces the current Data Provider and Data Aggregator Agreements and governs what Europeana may or may not do with the data of the different aggregators through its web activities.

The Agreement will come into force on January 1, 2012, but EUscreen is proud to be at the forefront and one of the early adopters in this bold step forward for opening European cultural heritage to wide audiences.

>From the Europeana office: The Europeana Data Exchange Agreement is the result of a year-long process of consultations with the whole network of content providers and aggregators contributing to Europeana. The results of these consultations and other documentation can be found on the Europeana Towards a New Agreement pages.

The major revision in this new agreement, is that the metadata provided by the Europeana aggregators will now be released under a Creative Commons Universal Public Domain Dedication. This is in line with the recommendations of the New Renaissance Report of the European Commission’s “Comité des Sages” and the promises of the Europeana Strategic Plan 2011-2015. It will revolutionize the sharing and linking of cultural information and place its producing institutions at the heart of discovery on the internet.
